Mycologia 



plants, inconspicuous, scarcely visible in age ; context white, too 

 thin to measure, being a mere membrane holding the tubes 

 together; hymenium quite even, white, cremeous where bruised, 

 with a slight rosy-avellaneous tint in dried specimens ; tubes 

 rather rigid, oblique, regular in shape and size, reaching i mm. in 

 length, concolorous within, thin-walled, the mouths rounded, 

 entire, exceedingly minute, 10 to a mm. ; spores minute, hyaline. 



Type collected on much-decayed wood in Troy and Tyre, Cock- 

 pit Country, Jamaica, January 12-14, 1909, W . A. Murrill & W . 

 Harris 855. Also collected on a standing rotten stub in woods at 

 Mooretown, Jamaica, November 22, 1902, F. S. Earle 541; and 

 on rotten wood in the forest at Alto Cedro, Cuba, March 19-20, 

 1905, F. S. Earle & W. A. Murrill 548. 



14. Poria Earlei sp. nov. 



Widely effused, continuous, inseparable, about 4 mm. thick; 

 margin inconspicuous, delicate, pure-white, scarcely apparent in 

 older specimens ; context white, practically disappearing with 

 age ; hymenium even, regular, glistening, milk-white, becoming 

 very faintly yellowish in dried specimens ; tubes angular, quite 

 regular, white within, very thin-walled, entire to somewhat 

 toothed, 4 mm. long, 5-7 to a mm. ; spores scanty, ellipsoid, rather 

 blunt at the ends, smooth, hyaline, 5 X 3-5 /*. 



Type collected on a rotten log on Rose Hill, Jamaica, 4,000 feet 

 elevation, October 30, 1902, F. S. Earle 297. This species has 

 longer and larger tubes than P. tenuipora, and they glisten dis- 

 tinctly when turned from side to side in the light. 



15. Poria corioliformis sp. nov. 



Irregularly effused over fallen leaves and the surface of de- 

 cayed twigs in continuous areas 1-2 cm. wide, inseparable, not 

 very thin, following to some extent the irregularities of the sub- 

 stratum; margin conspicuous, broad, finely tomentose, white to 

 cremeous, elevated at times as though about to project as a narrow 

 pileus ; context similar to the margin and quite conspicuous ; 

 hymenium somewhat uneven, cremeous, glistening; tubes quite 

 regular, rounded to somewhat angular, 1-1.5 mm. long, cremeous 

 within, rather firm and thick-walled for the genus, entire on the 

 edges, 4-5 to a mm.; spores subglobose, smooth, hyaline, 4/x.
